Attaching ferrite rings to motor and line cables
 In the case of PM230 Power Modules of frame sizes A to C (0.37 kW...15 kW)
with integrated class B filters, attach the colored ferrite ring to the motor power
cable in order to meet the requirements set out in EMC category C1 for
conducted interference emissions.
Colored ferrite ring for motor cables

- Attach the colored ferrite ring between the terminals of the motor power
cable and the shielding plate of the Power Module.
- Use cables which are shorter than 25 m. Ferrite rings may not be attached
to cables measuring more than 25 m (80 ft) in length.
 The required ferrite rings for PM230 FSA to FSC Power Modules with
integrated class B filters are included in the scope of supply for the product.
 In the case of PM230 Power Modules of frame size B (4 kW...7.5 kW) and
design C (11 kW ... 15 kW) with integrated class B filters, the gray ferrite rings
also have to be attached to the line cable in order to meet the requirements set
out in the EMC guidelines for radiated noise.
Ferrite rings for line cables

- Attach the gray ferrite rings between the terminals and the shielding plate
on the line cable.
 The gray ferrite rings are included in the scope of supply for the product.
